T1R Crankshaft Pulley, Anyone installed yet?

http://www.typeoneracing.com/catalog/produ...4&cat=89&page=1

Was wondering if anyone has installed this yet. About to make an impulse buy.

It states it's the same diameter as OEM, which is great for me. I did a search and saw where a few stated that the OEM pulley had a balancer and any aftermarkets do not. Can anyone confirm or debug this for me? Rotational weight savings is a good benefit and besides removal this should be an easy mod for small to minimal gains.

Thanks.

I don't have the answers but theres some info on it in this group buy:

Yeah sadly thats the only thread on this modification with that specific part. I appreciate the link, and had already read that one.

Did anyone participate in that group buy, or did you guys opt for the fuel ionizer?

I just need to know if this part is going to cause accelerated wear due to a balance issue. Since it's the same diameter/size as OEM it won't cause the underdrive effects, just rotational weight savings.

Weight is what balances it. So I believe when you reduce the weight, you reduce it's effect to balance the crank.

I'm not certain but that's a good guess

LOL......I don't guess anyone would want to install it if it didnt work properly!!!!! It amazes me when these parts are advertised the way they are but the results are so bad/negative.

Now i am not a fan of the T1R fuel ionizer, but i would have thought this part would have some positive results coming from this company and their strong followers.

I thought our motors are harmonically balanced? If so, this is not a mod I would do.

As for marketing stupid parts, all companies do it. They need money. If they can sell you something that is totally worthless that they can make some money on, they will. Just because T1R makes some BS parts for profit making, it doesn't negate them as a company. HKS, Greddy, Mugen, etc all make LOTs of bullsh!t parts...probably almost 60% of their parts are total BS.

I would figure that the balancing would be done on the crankshaft itselfor atleast something more reliable. Not by some cheap flywheel spun by a belt. When you say harmonically balanced, does that mean the flywheel will be weighted somewhere?

Balancing, and harmonic dampening are different. The pulleys weight is important for the longevity of the motor. You have to remember the difference between street and race parts. If you can afford rebuilds for an all out race motor, go for it.

This is my D/D, so I don't need anything killing it off sooner than normal. The advertisement makes it seem so

So you are saying the flywheel acts as a dampener?

dam right man. there has been a few products in the health care industries using pseudo-scientific jargons/medical/dental concepts to fool consumers. Always look for reputable science magazines and science sources that test & evaluate these products. Some products can pass FDA but provide no real true benefit to consumers. I have spend some of my time at the dental clinic to answer and inform my patients to stay away from the scum&filth of the earth companies like this.
I emailed Honda Tuning about this light weight pulley set from orthodox, tracey sports, ...ect and I am waiting for a reply. Fot the time being, I would not put this thing in my car.

Will you let us know what they say if you get a response?

Thanks.

I will I suspect if we are going to use this pulley set, we might have to re-tune/modify the engine to cope with these changes. Tracey sports & some of the nismo, acura, toyota, lancer & wrx engines in Dsports, Modified, Superstreet magazines...ect are all modified engines. Now for the stock engine such as the s2000, I would think carefully about it.

I would agree on anything underdrive, but the T1R is same size just lighter in weight. I wouldnt touch an underdrive pulley set for my car.

Ok here is "Sam's" reply from T1R.

This won't caue premature wear on the motor as the size of the pulley is made to OEM sizing but much lighter and stronger.

Why would this affect the balance of the motor?

Sam

So my question is is this thing really playing a part in harmonizing or balancing the motor? Either he seems like he doesnt want to address the situation or we are mistaken.

In 50,000 miles when your engine does fail. Can you point your finger back at the crankpulley?

I doubt it

Well first of all i wont be installing this part NOW.

But if i werent worried about my motor or believed what T1R wrote to me then i would. And I have an email from a rep from T1R stating it wouldnt cause damage. See above post. And if I COULD trace it to a faulty part i would definitely pursue some sort of rembursement. These companies shouldnt be able to advertise like they do and get away with it. And before anyone gets tore up and tells its my fault and my responsibility, i understand and took precautions by asking around. There is no "race use only" disclaimer or anything. So how is anyone supposed to know upfront? There are a lot of people that could be mistaken about bolt ons like this.

Yes, agreed with what everyone here has said about the crank pulley. Please do some research on this board on lightened crank pulleys and you'll see that it's not a good idea.

Boy how did it take so long for ol' "use the search button" comment to arrive!!! LOL

I ALWAYS use search first. Just because that sign over <<<<there says "guest" doesnt mean i dont. Not trying to be an azz but not too much came up on my 3 search attempts i performed. And like i said the OEM even said it wouldnt.

Can a guy not get pie eyed and make an impulse buy? GEESH!

It's not a question of it being lighter or not. The problem is it has no harmonic balancer built into it to absorb the harmonics the motor is puts out. Trust me, I would love to be able to replace the OEM crank pulley because it looks like arse next to my nice blue accessory pulleys.

Does it really need to be stronger . I've never heard of a crank pulley failing .

I don't get Sam's reply. What does balance, or the pulleys diameter have to do with its ability to remove harmonics? It's a lighter metal, which is less dense, which is more likely to resonate. The lack of a damper also means the crank has to absorb all shock load put on it by the accessories.

Well i have a better one for you. Here is his second reply.

Changing this to the lighter weight crank pulley wont have affect int he balance. dont worry.

So i am at a loss for words here.

He doesn't get it. We know it's balanced Sam, where worried about dampening.

Ok.....i will ask this and see what i get. Stay tuned!!!!!!

The accessories don't put any shock load on the crank pulley.

It's not the shock load of the pistons per say, but the resulting resonance harmonics that need to be controlled.

I would imagine the compressor locking up would torque the crank a little, but I realize the main function of the rubber is to kill harmonics. I wish my fingers typed as good as my brain thought.
